Abstract

The invention discloses an airborne wireless data communication relay unit residual-life prediction method and device and aims to solve problems that health status of an airborne wireless data communication relay unit cannot be rapidly and accurately predicated due to noise interference and complex changes of health factors during diagnosing and predicting of the health status of an existing airborne wireless data communication relay unit as well as original test data files of the airborne wireless data communication relay unit are not neat in specification and cannot be directly processed. The predication method includes: preprocessing test data; performing trend predication on the health status of the airborne wireless data communication relay unit and acquiring prediction time that faults occur, namely the residual life of the relay unit, according to fault thresholds, wherein trend prediction of the health status includes direct health factor prediction and indirect health factor prediction. The prediction method is applied to a data transmission system.
